BCX56-16-QX

Overview

The BCX56-16-QX is an NPN medium power transistor from the Nexperia BCX56-Q series, housed in a SOT89 (SC-62) surface-mounted plastic package. It features a collector-emitter voltage of 80 V and a continuous collector current of 1 A, with a peak pulse current capability of 2 A. The device offers three current gain selections; the -16 variant provides a DC current gain range of 100 to 250 at IC = 150 mA. Qualified under AEC-Q101 for automotive applications, it supports a junction temperature up to 150 °C and includes specific thermal resistance characteristics for PCB mounting.

Procurement Notes

Verify the specific ordering suffix matches the required current gain bin, as the BCX56-Q series offers multiple hFE variants. Confirm that the SOT89 package footprint aligns with the target PCB design guidelines provided in the datasheet. Ensure compliance with automotive qualification requirements if deploying in vehicle electronics. Check for any recent product change notifications regarding manufacturing updates or material composition changes.

Selection Notes

Select the BCX56-16-QX when a high DC current gain between 100 and 250 is required for amplification or switching tasks. Consider the SOT89 package for its balance of power handling and surface-mount convenience. Evaluate the thermal resistance values against the expected ambient temperature and PCB copper area to ensure safe operation within the 150 °C junction limit. Compare against other series members if different gain ranges or lower cost options are acceptable.

Part Context

This component belongs to the Nexperia BCX56-Q series of NPN medium power transistors. The series is designed for robust performance in both industrial and automotive environments. The Q-series designation indicates adherence to AEC-Q101 stress test qualifications. The SOT89 package provides a flat lead design suitable for efficient heat dissipation compared to smaller signal transistor packages.

Replacement Considerations

BCX56-10-Q and BCX56-Q are part of the same series with identical electrical ratings but different current gain specifications.
